在本文中，我们研究的影响ofheterogeneity的链接权重，异质性的频率或数量的个体之间的相互作用，对合作的演化。通过对具有个体内部异质性的一维加权格子网络上的进化囚徒困境博弈的分析，证实了适度的链接权重异质性有利于合作.此外，我们确定了链接权重异质性促进合作演变的两个关键机制：合作的传播和维持机制。我们还推导出相应的条件下，该机制可以通过进化动力学的工作。
In this paper, we investigate the effect ofheterogeneity of link weight, heterogeneity of the frequency or amount of interactions among individuals, on the evolution of cooperation. Based on an analysis of the evolutionary prisoner’s dilemma game on a weighted one-dimensional lattice network withintra-individual heterogeneity, we confirm that moderate level of link-weight heterogeneity can facilitate cooperation. Furthermore, we identify two key mechanisms by which link-weight heterogeneity promotes the evolution of cooperation: mechanisms for spread and maintenance of cooperation. We also derive the corresponding conditions under which the mechanisms can work through evolutionary dynamics.
